So NO rabbit CAS in pets?

Some of the replies in this thread are really off. I think putting horses into a closed world is an absolutely ridiculous idea, no matter how many people are assumed to like them more. There aren't even any cars, so where would sims ride a horse? Around a 2x2 lot? That doesn't sound very exciting.

I agree with you OP, rabbits would seen to suit TS4 more than a useless horse.
